Of course this is only ideal in neighborhoods where people still look out the window when car alarms go off. This is not going to work in a city; where residents just curse and throw a shoe at the wall to be bothered by yet another annoying car alarm.
For those who live near people who have been desensitized to car alarms, might I offer further advice. Keep a fog horn, pepper spray, and a high powered flood light (flashlight will do) next to your car keys. Assault all of your intruders senses, while renewing those of your close neighbors. You're not going to make new friends by doing this, but on the bright side...no one will come to your door to complain. Well, at night anyway.
I joke, but your personal safety is important. It seems like every time you turn on the news there is another home invasion or burglary attempt. We have had some horrifying ones here in Connecticut. So, do what you can to keep you and your family safe.
If you have any good ideas related to this please let me know.
